1 Specification forming part of Letters Patent N0. 17,909, datedJulyQcl, 1857.

To all whom it may concern:

Be it known that we, HARRISON ()GBORN,

- of Greens Fork, county of Wayne, and State of Indiana, and GEORGETAYLOR, of the city of Richmond, in the county of \Vayne and State ofIndiana, have invented a new and useful Machine forPlowing Corn; and wedo hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,in which- Figure l is a perspective view of the machine, the driversseat and-onewheel being re moved to show the arrangement of parts moreperspicuonsly. Fig. 2 shows the relation of the beams g with theguide-bar O. Fig. 3 is a section of axle F, showing the eccentricity ofthe spindles. v

A B B G constitute the frame of the machine. These parts should bepermanently framed together in any suitable manner. The cross-bar Areceives the tongue or perch on its front side. Upon its rear are drivenstaples for the retention of the rod K. The sides B B receive spindlesof the shaft F. The bar 0 is shaped, as shown in Fig.2, so as toaccommodate plow-beams g ggg of different lengths. It'has also two setsof middle guides, c 0, to allow of adjustment of the plows to or fromthe plants.

D is a pole or tongue; E, one of the carriagewheels; F, an axle witheccentric spindle. It answers a double purpose-via, as an ordinary axle,and also an eccentric for gaging the depth of the plows. It is retainedin any desirable position by spring-catch m.

G G G G are plows of any ordinary form. H is a Windlass by means ofwhich the plowheams g'are lifted.

I is a treadle connected with windlass H by means of strap 1', and bymeans of which the driver is enabled to lift the plows with his foot.

h h h h are cords connecting windlass H with plow-beams g g g g.

k k are supports to Windlass H.

K is a rod retaining plow-beams g g g 9.

Operation: This plow is drawn by two horses, one passing on each side ofthe row of corn, two of the plows also passing on each side of the row,and the machine striding over the corn. V The treadlc is used at eachend of the row to lift the plows while turning, and also while passingover any obstruction.

'This invention, though at first sight apparently similar in one,of itsparticulars to the claim of D. B. Rogers, is yet quite dissimilar inthis particular, that whereas he uses a crank axle-tree in combinationwith a cultivatorframe, we claim an eccentric axle in OUIllbZlliltionwith plow-beams g g g g.

Now, we do not claim the combination of a crank axlctree extendingacross the center of the frame, on the ends or cranks whereof aremounted the Sustaining-wheels, the same being for the purpose of raisingand lowering the frame of the cultivator, as shown and described in D.B. Rogers patent of January, 1849; but

We do claim as new and useful and desire to secure by Letters Patent Thecombination of plow-beams g g g g with the eccentric axles F, in themanner and for purposes herein set forth.
